MACHINE FOR WORKING ON CANS.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed March 21, 1916. Serial No. 85,635.

To all whom it may concern:

Be it known thatI, PETER Know, a citizen of the United States ofAmerica, residing in the borough of Brooklyn, county of Kings, city andState of New York, have invented certain new and useful Improvements inMachines for Working on Cans, of which the'following is a specification.

This invention relates to machines for working on cans, as, forinstance, seaming machines, and aims to provide improvements therein.

The present invention embodies an 1mrovement upon that set forth in myUnited States application Serial No. 54,756, filed October 8, 1915. Bythe present invention means are provided for shaping or rounding thecans in seaming, or other position, and there is further provided acombination, or combinations, of such shaping means with other elementsof the ma chine, especially the can-feeding mechanism and theend-feeding mechanism. The invention further provides improvements inthe end-feeding mechanism.

Other features of improvement will be hereinafter referred to.

An embodiments of the invention is illus trated in the accompanyingdrawings, in

connection with which the invention and its embodiment will be morefully described.

In said drawings, Figure 1 illustrates, partly in side eleva tion and invertical section, part of a machine for seaming heads on cans, andembodying the present invention.

Fig. 2 1s a horizontal section, on the line IIII, of the machine shownin Fig. 1.

Fig. ,3 is a diagrammatic view illustrating the action of the feedingmeans in feeding cans to a working position.

Fig. 4 is a detail view of a part of the end feed mechanism.

In said drawings, letter A designates a mechanism for feeding cans, orcan bodies, to a working position, B a mechanism for feeding can headsor ends to the cans or can bodies, C a mechanism for working on thecans, as for instance a seaming mechanism, and D a mechanism forejecting cans from working position. 7

The feeding mechanism A preferably comprises a disk j having one or morefeed-fin gers J thereon. The disk j may be mounted upon a vertical shaftj, and may be rotated by a chain and sprockets j j, the sprocketsreceiving motion from a vertical drive shaft 0.

The feeding mechanism A acts to feed the cans to a position where theyare to be acted on by suitable mechanism, as for example the seamingmechanism C.

It is desirable to accurately position cans or can bodies in the workingposition, and also to shape or round deformed cans which are fed to aworking or other definite position. The positioning, and the shaping orrounding of cans is of advantage in the case where the cans or canbodies are to be supplied with heads or ends, and especially where theheads or ends are supplied to the cans or bodies in a working position,as is preferable in the present invention. The feed-fingers Japproximately position the cans in working position. Oont1guous to theposition of the cans or can bodies in working position there is providedan abutment R, which may be suitably fixed to the casing or column ofthe machine, and which preferably has a straight edge 1". Opposite theabutment R there is arranged a movable part S, having a semicircular, orother appropriately shaped, opening therein, which is adapted to embraceand press the can or can body against the abutment R. By the conjointaction of the abutment R and the movable part S, the cans or can bodiesof a degree of deformity capable of being corrected by the machine areaccurately positioned and shaped, or rounded to a degree permitting ofthe reception of the heads or ends.

In the embodiment shown, the machine comprises a pad H which is adaptedto lift the cans or can bodies into position to be operated upon by theseaming mechanism O, or other appropriate mechanism for working on thecans. The pad H may be raised and lowered by a slide it actuated by acam piece [L on the rotary shaft 0.

After the cans or can bodies have been acted upon by the workingmechanism they may be fed forward or ejected by suitable feeding orejecting means D preferably being operatively connected to the maindriving mechanism independently of the means for feeding the cans to themechanism for working on the cans. This means preferably comprises afinger n which is carried by a collar at around an eccentric a fixed onthe rotary shaft 0. The collar n has a tail-piece a having a slidingconnection with a pin n. The action of the eccentric upon the collar nis to give the finger M an elliptical orbital movement. The movement ofthe finger of is such that after pushing the can or can body from theworking. position, it moves around, out of the Way of thecan or can bodywhich may be being fed by the feed arms J, into positlon to again push acan or can body from working position. The can, when pushed out ofworking position by the ejecting means, may go on to a deflecting plateP from whence it may pass from the machine.

A means for feeding can heads or ends to the cans or can bodies inworking position, is preferably included. This means preferably includesa table on having a suitable magazine or hopper m thereon for holding astack of'can heads orends, and a slide m The slide may be reciprocatedby means of a rod m lever m and link m, the rod m preferably receivingmotion from a crank disk m which latter may be suitably driven from therotary shaft 0 through sprockets m and m and a chain 021*. The slide mis provided with an opening on and has in flected or incurved ends m. Aledge m is provided upon which the edges of can heads orends which arecarried by the slide, are adapted to rest.

hen the opening m in the slide is beneath the hopper m a can head or enddrops upon the ledge m and, upon the lide moving forward, the can heador end resting upon the ledge m is separated from the other can heads orends in the stack and carried forward. The movement of the slide m is sotimed with relation to the pad H and its actuating mechanism, that thecan head or end is lifted from the ledge on on the slide as the can'orcan body is moved into position to be worked on by the seaming rolls.When the can head or end is not lifted from the slide by the can or canbody, the inflected ends of the slide maintain the can head on theslide, the can head being carried by the slide away from the positionwhere the ends are fed to the cans or bodies. Thereby the actual feedingof the can heads is dependent on the presence of a can or can body toreceive it.

As the slide m moves the can head into position over the can or canbody, the positioning and shaping means may be arranged to act upon thecan or can body, so that the can body is accurately positioned and heldto shape, or approximately to shape, when it comes into contact with thecan head or end on the ledge m.

The part S of the can-positioning and shaping means may be convenientlymounted upon the slide m as illustrated inthe present embodiment.

As the slide m is actuated by a crank, there is a virtual dwell in theslide m and the part S carried thereby, when these parts are in theirforward position to present the can head to be lifted, and to positionand shape the cans or can bodies. A stop m" contacting with the end ofthe slide m effects a positive dwell of the slide in the positionthereof with the ledge m beneath the magazine.

In order to improve the action of the slide m in separating can headsfrom the underside of the stack in the magazine, the slide is providedwith a separator or knife we (see Fig. 4), and the opening in the slideis preferably made so that the can heads have a suficient amount of playto fall below the knife edge, and onto the ledge m. On the feedmovementof the slide, the knife-edge enters between the edges of the lowermostcan head in the stack and the one above it, separating the bottom canhead or end from the stack. The position of the can head on the slide,as the can head drops from the magazine, is indicated by the dotted linem, Fig. at, and the position of the can head on the slide when the knifem has entered between it and the can head above it, is shown by the fullline at. While the can heads may have a slight amount of play on theslide, yet the inflected ends m prevent the can head from passing off ofthe slide edgewise.

Cans or can bodies having a head 'or 100 end on one end thereof, whendeformed, are usually elliptical in cross-section, the ellipse taperingtoward a circle when the head or end on the end of the can is circularin shape, and it is advantageous that the 105 deformed can bodies be sopositioned in the position where they are acted upon by the positioningand shaping means, that the major axis of the deformed can bodiesbe inline, or substantially in line, with the direc 11 tion of motion of thepart S of said positioning and shaping mechanism. The feeding means A ispreferably such as to accomplish the feeding of deformed cans in suchmanner that the deformed cans, when ap- 115 proximately positioned, havetheir major aXis in line, or substantially in line, with the directionof movement of the shaping or rounding part.

Referring to Fig. 3, when the feed arm J 120 comes into contact with adeformed can body, the position of most stable resistance to the actionof the feed arm will be that in which the minor axis of the ellipse is'perpendicular to the feed arm. This relation 125 of the feed arm willcontinue until the end of the feed arm is in the neighborhood of theminor axis. At this point, and at points of contact between the end ofthe arm J and the sides of the deformed can body beyond 130 stantiallyin line, with the direction of movement of the movable part of theshaping or rounding mechanism. The nonradial mounting of the arms J onthe disk j isof advantage in carrying out the positioning of the'deformed can as just referred to. Undeformed cans will be pushed forwardin an ordinary manner into position to be acted on by the positioningmeans, the cans be ng accurately positioned by the positioning mechanismif they are not so positioned b the feed mechanism.
